RADIATOR.

Application led June 21,

My invention relates to radiators and has among its other objects theproduction of Vdevices of the kind described which are convenient,durable, etlicient and satisfactory for use wherever found applicable.

A particular object of the invention is to provide anv improved deviceof thekind described comprising sheet metal stampings which can bequickly and easily assembled with each other. e .i Another particularobject of the invention is to provide a radiator for an automobile orthe like having improved means for causing the air passing through theradiator to come into Contact Awith all portions of the water tubesthereof. v

rMany other objects and advantages of the construction herein shown andwill be obvious f to those skilled in the art from the disclosure hereingiven. To this end my invention consists in the novelconstruction,arrangement and combination of parts herein shown anddescribed, and` morey particularly pointed outin the claims. i

.In the drawings, whereinV like reference l characters indicate like orcorresponding lparts:` Y

Referring for the presentto Figs. 1 to 5, Y

inclusive, wherein I `have shown'onefform of the inventionV embodied inan automobile radiator designated generally by the reference character1Q, the' reference characters 12 and 13 designate the upper and lowertanks, respectively, of the radiator.

tanks 1,2v and 13 communicate with "each Awhich are preferably formedfrom relative- 1y thin sheetmetal and are preferablyl yot' described The1,926. Serial No. 117,252.

elongated cross section, as best shown in Figs. 2 and 3. The tubes 14are preferably formed with a seam 16 extending longitudinally of oneedge thereof, the seam 1,6 being i the central'portion of the tube.`This aids in the exchange of heat from t-he water t'o the air flowingthrough the radiator. ,The longitudinal edges are preferably arcuate asat 18, one arcuate edge 18 having the seam* 16 formed therein. v'lfheseamv 16 preferably projects outwardly from the tube so that it maybe quickly and easily soldered, or re-k solderedif'it becomes damaged inuse".`

The upper and lower ends of the tubes 14 preferably' project tln'cughheader plates 19 and are preferably, soldered thereto, the

plates being soldered or otherwise secured to the tanks 12 and 13.However, it is readily understood that in someinstances I may prefer todispense with the header platesb 19 `and solder the tubes 14 directly'to they tanks 12 and 13.

Associated.l with the tubes 14 and prefera.

bly soldered thereto are aplurality of cooliing fins 22 which in thisembodiment of the l invention are stamped from relatively thin l,thereto, each iiny being soldered to onek vof the pair of fins solderedvto an adjacent tube 14.

in the same plane, and a plurality of spaced portions 25 disposed ,in asubstantially paralflel plane. The portions 25 are disposedlintermediate the .portions 24 and arejoinedl theretovby,.inclincdportions 26.. Formedy 1n each portion 24 is a relativelylarge depression 28 .adapted to` accommodate one-half of thecircumference of one of the tubes 14,

I Each of the 22 comprises4 a plurality of spaced portions24 disposedsubstantially .a smaller depression 29 forming an extension f.

- onehalf of the seamy 16. The depressions other through a plurality vofwater tubes 14 i' 28 and 29 are best shown in Figs. 3V and 5,A Fig. 5being view of one of the fins 22 look# i at the side thereof in vwhichtherdepresv inthe portions is formed into ribs 35.

sions are formed. Rows of hollow buttons or projections 31 arepreferably stamped in the portions 24 and 25 to facilitate the task ofaligning the fins with each other during theassemblyof the radiator,theconstruci tion being such that the projections formed upon one finwill extend into in the projections formed upon the other fin (See Fig.`

3). However, it is to be understood that in the preferred embodiment ofthe in-vention the fins are identical in construction and it is onlynecessary to reverse oneof the fins with respect .to another when it isdesired tohave the projections of one extend into the projections of theother. p

"Formed in the portions 25 are deflecting portions 33 which are adaptedto guide air `passing through the radiator so that the air fiowsaroundthe rear edges of the tubes 14 l(see Fig. 2). This insures. thatthere will bean efficient exchange ofheat through the rear` edges of thetubes 14 and the air Jpassing through .the radiator. The surplus metal.which also VContact Awith airpassing through thelradiatorand aid 'inthe exchange of heat between the water tubes and the air.V In y thepreferredrembodiments of the invention the fins 22 Vare soldered to eachother and to the tubes 14- so that the assembled struc- V ture isrelatively rigid.

Y In Fig. 6 I have shown another form of the invention einbodiedinradiator construction wherein a row of front water tubes V40 deredatanytime should they need repair- Soldered to the tubes 40 .and 41 area ing.

plurality -of cooling fins which vresemble the aforementioned coolingfins 22 in structure but differ therefrom by being provided with bothfrOIlt'and rear depressions 47, for accommodating the front andreartubes 40 Eand 41, respectively. vThe cooling fins 45 falso differ in`construction from thefins 22 vby. being provided with two rowsofdeflecting portions 49 in place of the deflecting portions 33 providedin .the fins 22, v`The front deflecting portions 49 insure that airpassing through the radiatorwill be brought intointimate contact withthe rear edges of ythe ,front .tubesj40vandthe rear defleoting`portioiis49 insure that the air will come in yContact ywith therearwardly disposed edges `of vthe-reartubes 41. With the .eX- ceptionsnoted, the fins 45 are substantially identical with the fins 22 and maybe assembled with the tubes 40 and 41 in substantially the saine manneryas the fins 22 are assembled with the tubes 14.'

Having thus described 1my invention, it is obvious that variousimmateriall modifications may be made in the same without departing fromthe spirit of my invention; hence I dov not wish to be understood aslimiting myself to the exact form, construction, arrangement andcombination of parts herein shown and described or uses mentioned.
